Negative schizotypal traits may be related to anhedonia and/or amotivation; however it is unclear which of these symptoms is related to negative schizotypy to a greater extent. Moreover, the impact of schizotypal traits on overall subjective well-being remains uncertain. The present study examined these two questions in a non-clinical sample assessed for schizotypal traits (n = 138). Schizotypa...

BACKGROUND Schizotypal personality traits are associated with schizophrenia spectrum disorders, stating that schizotypal traits may represent a "prodrome" or other developmental precursor of schizophrenia. Genetic and environmental factors both play importanxt roles in the development of schizotypal traits. Different levels of schizotypal traits across regions may be indicative of similar diffe...

Schizotypal traits are of interest and importance in their own right and also have theoretical and clinical associations with schizophrenia. These traits comprise attenuated psychotic symptoms, social withdrawal, reduced cognitive capacity, and affective dysregulation. The link between schizotypal traits and psychotic disorders has long since been debated. The status of knowledge at this point ...

The relationship between self-reported social functioning, schizotypal traits, and obsessive-compulsive symptoms (OCS) was studied in a sample of 508 adolescents, of which 49.8% were male adolescents, with a mean age of 14.9 (SD, 1.6). The Schizotypal Personality Questionnaire-Brief, Maudsley Obsessive-Compulsive Inventory and Social Adaptation Self-evaluation Scale was administered. The result...

OBJECTIVE Schizotypal personality traits are associated with schizophrenia spectrum disorders, and individuals with schizophrenia spectrum disorders demonstrate increased dopamine transmission in the striatum. The authors sought to determine whether individual differences in normal variation in schizotypal traits are correlated with dopamine transmission in the striatum and in extrastriatal bra...

OBJECTIVE Investigating the factor structure of schizotypal traits in normal population is important to describe the clinical phenotypes associated with susceptibility to schizophrenia. Schizotypal Personality Questionnaire (SPQ) is a commonly used self-rated measure to assess schizotypal traits. While Raine's three-factorial model is most commonly supported model explaining factor structure of...

Existing self-report measures of schizotypal personality assess only one to three of the nine traits of schizotypal personality disorder. This study describes the development of the Schizotypal Personality Questionnaire (SPQ), a self-report scale modeled on DSM-III-R criteria for schizotypal personality disorder and containing subscales for all nine schizotypal traits. Two samples of normal sub...

The main objective of the present investigation was to analyze the relationship between self-reported schizotypal and borderline personality traits in a sample of 759 college students (M = 19.63 years; SD = 2.03). For this purpose, the Schizotypal Personality Questionnaire-Brief (SPQ-B; Raine and Benishay, 1995) and Borderline Personality Questionnaire (BPQ; Poreh et al., 2006) were administere...

The brain derived neurotrophic factor (BDNF) val66met polymorphism rs6265 influences learning and may represent a risk factor for schizophrenia. Healthy people with high schizotypal personality traits display cognitive deficits that are similar to but not as severe as those observed in schizophrenia and they can be studied without confounds of antipsychotics or chronic illness. How genetic vari...
